********> bugfix.52
Author:   Bill Ross
Date:     10/31/95

Programs: Carnal

Severity: Slight

Problem:  If FILES_OUT section COORD (coordinate output) is defined 
          but not connected to a stream via a corresponding COORD in the 
          OUTPUT section, program attempts to write undefined coords 
          to file and may crash.

Cause:    Not checking if user completed the COORD definition.


Fix:  Make the following change to doit.c:
------------------------------------------------------------------------
*** OLD doit.c
--- NEW doit.c
***************
*** 128,137
  					closetab(idptr);
  				break;
  			case CRD:
! 				if (someser)
! 					writecrd(idptr, 0);
! 				else {
! 					writecrd(idptr, 1);
  					closecrd(idptr);
  				}
  				break;

--- 128,143 -----
  					closetab(idptr);
  				break;
  			case CRD:
! 				if (someser) {
! 					if (idptr->idunion.crd.set != NULL)
! 						writecrd(idptr, 0);
! 				} else {
! 					if (idptr->idunion.crd.set != NULL)
! 						writecrd(idptr, 1);
! 					else
! 						printf(" ** Note: COORD %s %s",
! 						  idptr->id_name,
! 						  "not defined in OUTPUT\n");
  					closecrd(idptr);
  				}
  				break;
------------------------------------------------------------------------

Temporary workarounds: Complete all COORD definitions.
